BOSTON COLLEGE AT VIRGINIA TECH
When: noon, ACC syndication/ESPN GamePlan
Broadcasters: Tim Brant play-by-play, Doc Walker analyst.
Line: Virginia Tech by 13.5
Why you should watch: Boston College has won each of the past three regular-season matchups, but Virginia Tech has beaten the Eagles in each of the past two ACC championship games. Boston College is the only team in the Atlantic Division with two league wins, and both have come against division opponents. The choice to start 25-year-old true freshman quarterback David Shinskie, a former minor league baseball player, has jump-started Boston College's offense. BC needs a big game from running back Montel Harris. After allowing 5.3 yards per carry through the first three games of the season, Virginia Tech has regrouped to allow only 1.5 yards per rush in its past two games.

ALABAMA AT OLE MISS
When: 3:30 p.m., CBS
Broadcasters: Craig Bolerjack play-by-play, Steve Beuerlein analyst.
Line: Alabama by 6.5
Why you should watch: Preseason prognosticators couldn't find a consensus on how the SEC West would shake out between Alabama, LSU and Ole Miss. Thus far, Alabama appears to be the strongest of the three, while Ole Miss already has to play catch-up because of its 16-10 loss at South Carolina on Sept. 24. Ole Miss quarterback Jevan Snead entered the season with more fanfare, but Alabama's Greg McElroy completes a higher percentage of his passes, averages more passing yards per game and owns a better touchdown-to-interception ratio. Alabama is in the top four nationally in run defense and total defense. If Ole Miss is going to play in its first SEC championship game - the Rebels are the only Western Division team never to reach that plateau - it needs to beat Alabama for the first time since 2003.

WISCONSIN AT OHIO STATE
When: 3:30 p.m., ABC/ESPN/ESPN GamePlan
Broadcasters: Sean McDonough play-by-play, Matt Millen analyst.
Line: Ohio State by 14½
Why you should watch: Wisconsin is 5-0, but the Badgers aren't getting much respect. Wisconsin is ranked 25th in the coaches' and Harris polls and is unranked in the AP poll. Rest assured, the Badgers will be ranked if they win in Columbus. Wisconsin sure looks like a team returning to form after a disappointing 7-6 season a year ago. John Clay is a punishing runner who has averaged 32 carries and 163 yards in two Big Ten games this season. He and the Badgers' stout offensive line will test Ohio State's defense. The Buckeyes have allowed 113 total rushing yards in their past three wins. The big question for Ohio State is whether sophomore quarterback Terrelle Pryor is close to breaking out. Pryor led two fourth-quarter scoring drives to beat the Badgers 20-17 in Madison last season.

FLORIDA AT LSU
When: 8 p.m., CBS
Broadcasters: Verne Lundquist play-by-play, Gary Danielson analyst.
Line: Florida by 7.5
Why you should watch: The winner of this game has gone on to win the past three national championships. But who knows what we'll get when the teams meet Saturday night in Death Valley. Florida quarterback Tim Tebow, who has passed for six touchdowns and ran for three more in three games against LSU, returned to practice Tuesday after suffering a concussion against Kentucky, but he has not been cleared to play. If he does play, will he be limited in the running game? LSU may as well stand for "Lucky State University." The Tigers needed a goal-line stand to beat Mississippi State two weeks ago and took advantage of a dubious unsportsmanlike conduct penalty to beat Georgia in the final minute last Saturday.

MICHIGAN AT IOWA
When: 8 p.m., ABC
Broadcasters: Brent Musburger play-by-play, Kirk Herbstreit analyst.
Line: Iowa by 7.5
Why you should watch Which Michigan offense will show up in Iowa City? Freshman quarterback Tate Forcier and the Wolverines appeared ready to pick apart Big Ten defenses, but Michigan struggled in the first three quarters of last week's OT loss at Michigan State. Now, Michigan goes on the road again, this time against a defense that smothered Penn State in Happy Valley. The Hawkeyes have not allowed a rushing touchdown this season, and have picked off 10 passes in the past four games.
